DESCRIPTION
CLOCK SIGNALS (CONTINUED)
CLKOUT
/IOPD0
5
12
I/O
O
Clock output. This pin outputs the CPU clock (CLKOUT) only. This pin can
be used as a GPIO, if it is not used as a clock output pin.
TEST SIGNALS
TCK
28
36
I
I
JTAG test clock with internal pullup
TDI
29
37
I
I
JTAG test data input (TDI) with internal pullup. TDI is clocked into the
selected register (instruction or data) on a rising edge of TCK.
TDO
30
38
O
O
JTAG scan out, test data output (TDO). The contents of the selected
register (instruction or data) is shifted out of TDO on the falling edge of
TCK.
TMS
31
39
I
I
JTAG test-mode select (TMS) with internal pullup. This serial control
input is clocked into the TAP controller on the rising edge of TCK.
TRST
32
40
I
I
JTAG test reset with internal pulldown. TRST, when driven high, gives
the scan system control of the operations of the device. If this signal is
not connected or driven low, the device operates in its functional mode,
and the test reset signals are ignored.
EMU0
37
48
I/O
I
Emulator I/O pin 0 with internal pullup. When TRST is driven high, this pin
is used as an interrupt to or from the emulator system and is defined as
input/output through the JTAG scan.
EMU1
38
49
I/O
I
Emulator I/O pin 1 with internal pullup. When TRST is driven high, this pin
is used as an interrupt to or from the emulator system and is defined as
input/output through JTAG scan.

I = input, O = output, Z = high impedance
The reset state indicates the state of the pin at reset. If the pin is an input, indicated by an I, its state is determined by user design. If the pin is
an output, its level at reset is indicated.
§These pins are internally pulled high. However, these pins are not pulled high in the emulation devices (’F243/’F241).
NOTE:
Bold, italicized pin names
indicate pin function after reset.
